Initialize from ROM algorithm

The aim of the initialize from ROM algorithm is to enable you to use an existing ROM (or range of motion) take to initialize a new take of the same actor and marker set. The function gives an efficient workflow for re-initializing a new take, using everything from the ROM take, including: camera calibration parameters, calibration brim structure, brim markers, facial markers, marker labels, and sticks.

Tip:          You can choose whether to initialize the full face and brim markers, or just the brim markers only.

Initialize from ROM uses the automatic tracking algorithm to match the brim markers and facial markers from a frame in the ROM take to a frame in the uninitialized take. Thus, the values set in the Tracking Parameters properties also affect the results of the Initialize from ROM algorithm. Note that the most useful tracking parameters for ROM initialization have been copied as a separate Initialize from ROM Parameters section, so that they can have different values for ROM initialization than for normal frame-to-frame tracking.

For example, if the positions of the facial markers in the current frame of the uninitialized take are a long way from the corresponding facial markers in the ROM frame, you may need to increase the Face Point Tracking Distance tracking parameter, and similarly if the positions of the brim markers are a long way from the corresponding brim markers in the ROM frame, you may need to increase the Brim Point Tracking Distance tracking parameter.
